Function core::arch::x86::_mm_mask_permutevar_pd

pub unsafe fn _mm_mask_permutevar_pd(
    src: __m128d,
    k: __mmask8,
    a: __m128d,
    b: __m128i
) -> __m128d

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512f,avx512vl only.

Shuffle double-precision (64-bit) floating-point elements in a within 128-bit lanes using the control in b, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
